11 C H A P T E R 2 This chapter is organized in four sections: • Rationale for TSP Deployments: Describes the context and operational problems that motivate the development of TSP and discusses how TSP fits with other transit-supportive treatments. • Current TSP Prevalence and Practices: Reviews reports and research papers that document the current state of the practice in North America and elsewhere.

12 Transit Signal Priority: Current State of the Practice variations. Adding layover time, which is usually time at the terminus of a route, can allow the route to recover from being late and gives the bus operator a chance for a small break.

Literature Review 13 Some studies have used the presence of buses to justify additional green time for bus approaches, which increases the probability of buses arriving on green and reduces their waiting time when they arrive on red (Skabardonis, 2000; Ma and Yang, 2007)

Literature Review 15 When TSP is implemented on intersecting bus routes, conflicting priority requests must be addressed at the signals where the bus routes cross. Different methods can be used to resolve conflicting requests, ranging from simple rules (e.g., first come, first served)
